Fundamental Cosmology with ESPRESSO and ELT-HIRES: I. Observational strategies for varying constants
Pedro O. J. Pedrosa
The observational evidence for the acceleration of the universe demonstrates that canonical theories of cosmology and particle physics are incomplete, if not incorrect, and that new physics is out there, waiting to be discovered. Here we discuss astrophysical tests of the stability of nature's fundamental couplings, studying the improvements that can be expected with ESPRESSO and ELT-HIRES and their impact on fundamental cosmology. We find that the current E-ELT configuration has the potential to constrain dark energy more strongly than standard surveys with thousands of supernovae.
